bought it stock and it would wheelie all day long!! now i have a full yosh exhaust, k+n, open air box, dynojet stage 1 jet kit,air filter sock, and other goodies. now when i clutch or throttle it into a wheelie it will want to stall out within 3 sec. it really pisses me off . dynojet says i have the right jets in it, and as long as i dont do a wheelie the thing is stupid fast with no problems at all

oh and thanks to the people who posted the raptor manual, oil filter ref chart. and mainly the reverse rev delete .

Yep, clear tube should do the trick! A buddy of mine was having the same problem and I did this to his quad and the problem was solved. It should be done anyway, you will love the throttle response! Here is a sticky from another forum with great pics and complete run down on how to do it...http://www.bluetraxx.com/phpBB/viewtopic.php?t=50521
